Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.
Answer:
Step-by-step explanation:
A to C
y = b + mx
b = y-intercept
m = slope of line
Looking at the line, the line crosses the y-axis at the coordinates (0,0). This means that the y-intercept is 0.
The slope formula is m=(y2-y1)/(x2-x1). Using the points on the line (-1, -3) and (1,3) we find that the slope is, 3.
Looking back we can see that our variables now have value so we can plug them into our formula.
y = b + mx
b = 0
m = 3
Substitute
y = 0 + 3x
Answer:
270 words per minute
Step-by-step explanation:
It is given 180 words in 2 minutes, this means Toni can type 180/2 = 90 words per minute (90wpm).
Thus, in the same ratio/rate, Toni would be able to type:
90 * 3 = 270 words per minute.
Correct answer 270 wpm
Answer:
Step-by-step explanation:
y=-1
because when y = - 1,
it is an equation of x axis.. hence it will parallel to x axis....
Answer:
49.55
Step-by-step explanation:
okay so, what we do is
Get 15% of 23
Get 15% of 32
15% of 23 is 3.45
15% of 32 is 4.80
Now we do
23 - 3.45
32 - 4.80
23 - 3.45 is 19.55
32 - 4.80 is 27.2
This is the part im not 100% on
27.20 + 19.55 is 46.75
6% of 46.75 is 2.80
46.75 + 2.80 is 49.55
Now i dont know if its that way or if you apply the 6% sale tax to each individual item
